Based on the chemotactic activity of approximately 50 different adenosine 3',5'-cyclic-monophosphate (cyclic AMP) derivatives with substitutions at the phosphate, ribose and adenine moieties, a model for the cyclic AMP-chemoreceptor interaction in Dictyostelium discoideum is proposed. In this model the cyclic AMP molecule is bound to the receptor by three hydrogen bonds at, respectively, the 3'-oxygen of the ribose and the 6-amino and the 7-nitrogen of the base, and possibly by one ionic interaction of the negatively charged phosphate group. The conformation of the adenine moiety is in the anti range and binds additionally to the receptor by hydrophobic interactions betueen its pi-electron system and a corresponding acceptor at the active site. Although this receptor clearly differs from that involved in protein kinase activation in higher organisms, the existence of striking similarities suggests a basic mechanism for cyclic AMP interaction conserved during evolution.
